<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <version>2.3.3.RELEASE</version>
    </dependency>

That is, add the above dependencies to the pom. You also need a startup class before,

package com.my.template;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
//springboot的启动注解
@SpringBootApplication
public class BootServer {
    public static void main(String[] args) {

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class TestServer {
    @ResponseBody
    @RequestMapping("test")
    public String test(){
        return "hello springboot";
    }
}
